The bombs targeted makeshift barracks and the military police headquarters, situated in two adjacent sealed off districts in the center of the city.
The successful attack was carried out by Noble Aleppo Brigade of the Free Syrian Army. 200 Assad soldiers were killed and wounded in it. Freedom fighters planted the bombs inside the buildings in co-operation with a loyalist sympathizer.
Meanwhile, Russian warplanes earlier bombed a residential district to the east and exacerbating a water shortage in Syria's biggest city after a pipeline burst.
Sunday's air raid destroyed a residential complex in the Hananu neighborhood, one of several in eastern Aleppo under freedom fighters' control.
The death toll was at least five, including one woman, and bodies and wounded people were being dug out from the rubble.
